The phrase "are used for precise" is not complete and lacks context, making it difficult to assess its correctness in written English.
It could be used in contexts where you are describing the purpose of something that is used for precision, but it needs to be part of a complete sentence.
Example: "These instruments are used for precise measurements in scientific experiments."
Alternatives: "are utilized for accuracy" or "serve to ensure precision."
Some of these are not too useful in paleontology, but the tiny tooth-like structures known as conodonts are used for precise age-dating and correlation of rocks ranging in age from Cambrian to Triassic and ostracodes are useful in all respects from the Paleozoic to the Recent.
Programmable nucleases, such as Cas9, are used for precise genome editing by homology-dependent repair (HDR 1,2,3.
For both types of solar trackers DC motor based servo systems are used for precise movement control.
The radiological properties of the stent are used for precise prostate localization during treatment using electronic portal images.
Scanning stages are used for precise positioning in a variety of advanced manufacturing processes, and must deliver high accelerations/decelerations at motion reversals to achieve high throughput.
COMPASS observations from a regional network of nine stations are used for precise orbit determination and clock estimation in simulated real-time mode, the orbit and clock products are applied for real-time precise point positioning.
The accidental intersections, however, occur at precisely known energies and can therefore be used for precise lattice-parameter determination.
The COSI-Corr technique was used for precise orthorectification, co-registration, and subpixel correlation of satellite data.
The slot antenna is used for precise operating frequency, where the frequency spectrum is 2.45 GHz and 5.5 GHz.
